css初始化代碼方案

爲了消除各瀏覽器對css默認的設置，保持網頁在各瀏覽器中的外觀保持一致，初始化css就顯得非常必要了！很多時候出現的樣式不兼容問題，都可以通過css初始化代碼來解決。下面列舉常用的一些方案：

1.最耗資源的，最簡單的

* { padding: 0; margin: 0; border: 0; } 

2.選擇性初始化舉例（綜合）

body,div,dl,dt,dd,ul,ol,li,h1,h2,h3,h4,h5,h6,pre,code,legend,button
form,fieldset,input,textarea,p,blockquote,th,td {   
　　padding: 0;   
　　margin: 0;   
}
/* 酌情修改 */
body {
    background:#fff;color:#333;font-size:12px; margin-top:5px;font-family:"SimSun","宋體","Arial Narrow";
}

/* 短引用的內容可取值：''或"" */
q:before,q:after {content:”;}  

/* 縮寫，圖片等無邊框 */
fieldset,img,abbr,acronym {border: 0 none;}
abbr,acronym {font-variant: normal;}
legend {color:#000;}

/* 清除特殊標記的字體和字號 */
address,caption,cite,code,dfn,em,strong,th,var {   
　　font-weight: normal;   
　　font-style: normal;   
}

/* 上下標 */
sup {vertical-align: text-top;}
sub {vertical-align: text-bottom;}

/* 設置表格的邊框被合併爲一個單一的邊框, 指定分隔邊框模型中單元格邊界之間的距離爲0*/
table {   
　　border-collapse: collapse;   
　　border-spacing: 0;   
}   

/* 表格標題及內容居左顯示 */
caption,th {text-align: left;}
input,img,select {vertical-align:middle;}

/* 清除列表樣式 */
ol,ul {list-style: none;}  

/* 輸入控件字體 */
input,button,textarea,select,optgroup,option {
    font-family:inherit;
    font-size:inherit;
    font-style:inherit;
    font-weight:inherit;
}

/* 標題元素樣式清除 */ 
h1,h2,h3,h4,h5,h6 {   
　　font-weight: normal;   
　　font-size: 100%;   
}   

/* 鏈接樣式，顏色可酌情修改 */
del,ins,a {text-decoration:none;}
a:link {color:#009;}
a:visited {color:#800080;}
a:hover,a:active,a:focus {color:#c00; text-decoration:underline;} 

/* 鼠標樣式 */
input[type="submit"] {cursor: pointer;}
button {cursor: pointer;}
input::-moz-focus-inner { border: 0; padding: 0;}

.clear {clear:both;}

}
ul,ol{

}
a{text-decoration:none;}
a:link{color:#009;}
